Product Description:

The Assioma PRO RS-1 is the lightest single-sided road power meter pedal on the market, weighing just 123.5 g. Built for Shimano SPD-SL cleats, it delivers professional-grade accuracy and performance—powered by a long-lasting battery that offers 60+ hours per charge with zero data dropouts.
Its innovative split-body architecture keeps the electronics and battery safely sealed inside the spindle, separate from the pedal body. This design ensures IP67 waterproofing, durability, and simple maintenance.
With a slim profile, +53 mm Q-factor, and 10.5 mm stack height, it’s optimized for efficiency and speed on the road. Powered by the IAV Power System, the PRO RS-1 ensures ±1% accuracy, even during sprints or with oval chainrings.
It also provides a wide range of advanced cycling dynamics and integrates easily with both Bluetooth and ANT+ devices. Thanks to its modular design, the same spindle can later be upgraded to a dual-sided system or paired with MTB pedal bodies.
A smart and precise tool for dedicated road cyclists seeking data-driven training and lightweight performance.
